Abstract
Described is a process for preparing and purifying 4'-chloro-4-biphenylcarboxaldehyde which comprises: (1) reacting 4'-chloro-4-biphenylcarboxaldehyde with sodium bisulphite in an aqueous/acetonitrile solution having an acetonitrile concentration sufficient to cause the bisulphite adduct to precipitate. (2) isolating the bisulphite adduct precipitate from the solution. (3) mixing the isolated bisulphite adduct in an aqueous/acetonitrile solution having a water concentration sufficient to cause a regenerated aldehyde to precipitate. (4) converting the bisulphite adduct to 4'-chloro-4-biphenylcarboxaldehyde.
